OVEN FOR GASOLINE-STOVES.

SPECIFICATION forming part of Letters Patent No. 386,676, dated July 24-, 1888.

Application filed Fcbinary 93,1858.

To all whom it may concern.-

Be it known that I, VALTER \VELLS, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, haveinvented certain new and useful Improvements in Ovens for Gasoline-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making apart of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view of my improved oven adapted for gasoline-stoves; Fig. 2, a longitudinal section taken on line at of Fig. 3; Fig. 3, a transverse scction taken on line ;1 y of Fig. 2, and Fig. 4 adetail view in perspective ofthe flamedeflector.

The present invention has relation to that class of ovens especially adapted for use on gasoline-stoves; and it consists in the details of construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents my improved oven provided with the sliding doors B, and at its top with handles a, the interior of the oven having the usual removable raeks, G. The two sliding doors B are provided with suitable handles for operating them, and are connected to the front side of the oven by guides 11, which are preferably formed from the same piece of metal that forms the front of the even, said guides serving as tracks upon which the doors work.

The top of the oven is provided with an airspace, 0, and the sides and top thereof have double walls d c, to form a space for the heat as it enters the interior of the oven to pass therefrom into the space through the openings f. The heat as it enters the interior of the oven passes in its course through the openings f in interior side wall, and thence out through the openings h in the outer side walls.

Vithin the oven, a suitable distance above the bottom thereof, is a hollow heating-plate, D, which communicates with the hot-air space at the back of the oven by means of perfora tions or openings i in the back inner wall. The deflector for the flame consists of a convex disk, E, which is provided with wire Serial No. $65,016. (No model.)

braces Ir, extemlingthrough thedisk, as shown, said braces at their extremities being bent downwardly, as shown at Z, and are connected to a ring, F. The ring F sets over the burner of the stove to retain it in position, and by the bend at the end of the braces It brings the disk the required distance above said ring to properly deflect and spread the flame, so that it will not be concentrated on any one portion of the hollow heating-plate I), but be distributed over its entire surface. \Vhcn the deflector isin position and the oven placed over it on the stove, the heat from the flame will circulate around the interior of the oven, pass through the openingsfg into the space formed by the double walls heretofore described, and after circulating around the space at the sides of the oven it will escape through the openings h. It will be noticed that the openings h are on a line with the lower one of the racks C, so as to keep as much heat from the bottom of the oven as possible and secure a uniforniity of heat both at the top and bottom of the oven, thereby preventing the danger of baking too fast at the bottom rack.

In order to prevent the bottom of the even from baking too fast, I. also form the heatingplate D hollow, as shown, and make provision for the heat that is generated therein escaping, which is attained by means of the perforations t in inner back wall of the oven, the heat escaping from the hollow plate through said perforations into the space formed by the double walls, thence escaping through the perforations g at the top of the inner back wall into the top of oven, and finally escaping through the openings 12. The perforations m. are for the purpose of supplying air to create a circulation to carry the heat back and up to top of oven. These perforations in front of the oven may, if desired, be dispensed with and other means employed for supplying to the oven the required quantity of air to produce circulation.

The oven is what is termed a knockdown oven-that is to say, it can be taken apart for the purpose of transportation or for storing away when not required for use; and to pro vide for this I construct the sides at both the front and back with flanges 12, which are bent over and against the walls (I to hold them in place. The sides above described are formed at their lower ends with inwardly-bent seats 0, to form a support for the flanged ends 1) of the inner walls, 0. The upper ends of these walls, like the lower ends, are bent outwardly to form a supporting-flange, r, for the hollow top which forms the airspace 0, to retain the heat in the top of oven. The walls 01 of the oven have flanges s, which are bent over said top to secure it in place, the flanges it also being bent over the hollow top to secure it at its top and back sides. By bending these flanges outwardly the several sections of the oven may be taken apart and packed for transportation, the racks 0 being first removed, also the hollow plate D, the latter simply resting on the supports 15 to.

In an oven constructed as above described a very simple, practical, and effective oven is provided which will do its baking thoroughly and uniformly.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oven for gasoline-stoves, the combination, with the double walls thereof at the back andsides, as shown, the escape-openings, and the openings through the inner ones of the double walls, of the hollow heating-plate and the deflector, the former communicating with the airspace back of the oven, and the outer wall provided with perforations m, communioating with the space within the hollow plate, substantially as and for the purpose set forth.

2. An oven for gasoline-stoves, formed in detachable sections provided with passages for the heated air at the sides and back thereo f, and communicating with the interior of the oven and with perforations m, in combination with the hollow heating-plate communicating with the passages, and a deflector consisting of a convex disk provided with wire braces and a connecting-ring, substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

WALTER WELLS.
